Zipper Dies


Zipper Bridge - The Zipper Bridge knits the clay back together, eliminating seam failure and cracking during drying & firing. It also allows for immediate manipulation of your extrusion into other forms.

Precision Radius Extrusion Dies - Very strong and smooth extrusion allows the clay to flow through the die into compression & flow out so you can work directly out of the extruder without sharp edges that could make your extrusion fail.

Variable wall thickness - Quickly & easily change the internal die to alter the wall thickness of your extrusion.

Highest quality material available - Durable & tough, made to engineering standards & precision.

Water and corrosion resistant - This tool should provide a lifetime of service.

A note from Michael: "My philosophy is that I can make any shape from a round shape & that a round extrusion makes the most consistent and strongest base for making almost anything. Working from my round extrusion I can pull the clay (in the same way you would pull when making a handle) & transform the round tube into a square or rectangular extrusion. This is particularly useful when I am making a lot of different components for a sculpture. When the whole sculpture is completed you would never guess that all the individual components came out of a round extruder. The possibilities are endless."

(Designed to fit a 4″ square extruder)
